Added comments on computation of IV_nz, IV_onz, IV_dnz. Used same loops preallocating/populating ZM_Net & ZM_A. Preallocation of ZM_A now uses 0 everywhere instead of only the diagonal with no effect on computations. Added comments on values used in preallocation of ZM_A. Moved computation of IM_index_up from matrix preallocation loop to matrix population loop. Added paragraph to display ZM_Net and ZM_A at the end
Added breaking connection for traditional Muskingum (IM_index_up) for forcing (bug fix) and dams. Added display of ZM_Net in stdout after modifs
Added display of ZM_Obs is stdout
